Hello Aspirant,

Admission number is a unique number assigned to you in an institute. You will be able to see your admission number at the top of the admission form , so you need to check the same. Moreover, institutes may send such details and information like applicant number , admission number etc through mail or an official admission letter . So you can find it out only by asking the respective admission authority of the institute or by checking such admission acknowledgments sent by the institute .

All the best
